well, how about you put a CD in and compare it to the MP3 Player turned all the way up but the stereo at the same volume? I bet you'll notice a difference then, that is what I was talking about, the needed difference in volume. Meaning, CD @ 10% Stereo Output = MP3 @ +10% Output. Get it now?

And in my case, an aftermarket stereo would cost alot more than getting my PAC Part that cost a whole $65.22
